FOLDING BUNK-STAIRS.

Specification of Letters Patent.

Patented nee. as, rare.

Application filed November 11, 191 1. Serial no. 571,504.

- Stairs, of which the following is a specification, reference being hadto the accompanying drawmgs. .7

This invention has relatlon to folding stairs, especially adapted to beused in con junction with the upper berths or bunks as used in sleepingcars, steamboats, and bunk houses.

The object of my invention is to provide stairs which can be compactlyfolded when not in use, to serve as a stool, the invention beingparticularly adapted to be used by porters in sleeping cars.

With these and other objects in view, the present invention consists inthe combination and arrangement of parts as Wlll be hereinafter morefully described and finally pointed out in the appended claims, it bemgfurther understood that changes in the specific structure shown anddescribed may be made within the scope of the claims without departingfrom the spirit of the invention.

In the accompanying drawings forming a part of this specification and inwhich like numerals of reference indicate similar parts in the severalviews: Figure 1, shows an elevational view of a bunk house showing anupper and lower bunk, to the upper bunk of which is attached a foldingstairs embodying my invention. Fig. 2, shows the stairs in its foldedcondition, adapted to be used as a stool. Fig. 3, is a top view of Fig.1, with parts broken away. Fig. 4, is a perspective detail of one of thetreads as used in my invention. Fig. 5, is a perspective view of one ofthe risers.

In my present invention I provide a folding stairs especially adapted tobe used in sleeping cars to enable a person to easily climb into anupper berth.

In carrying out the aim of my invention I employ a stool comprising thetop 1 and having the supportinglegs 18. To this top 1 are operativelyconnected a plurality of treads 1 and risers 9 of a size equal to thesize of said top 1. As disclosed each tread as well as the top 1' isprovided at its two forward corners with two downwardly extendingapertured ears 2, each ear having a securing base 3, by means of whichthe ear is secured to the tread. Secured to the two rear corners of eachtread are two upstanding ears 4, each upstanding ear having a securingbase 5 indicated in dotted lines in Fig. 4.

In connection with the top 1 and each tread 1, I employ a riser 9, oneof which is shown in detail in Fig 5. Each riser 9, isprovided with twooutstanding ears 10, secured to the two lower corners of each riser,while secured to the two upper corners of each riser are the outstandingears 12. They cars 10, have suitable openings and are provided with thesecuring bases 11, while the ears 12, also have openings and securingbases 13. By means of suitable pins'c, the cars 10, are secured to theears 1, so that each riser will fold upon the upper face of one treadand against the under face of the adjacent tread, as shown in Fig. 2.Pivotally securing each upper ear 12, to a downwardly extending ear 2,are the pins a, and these pins a, further give pivotal support to thetoggle bars 6 and 7, each set of toggle bars being pivotally connectedby means of a pin 8, this construction being best shown in Fig. 1.

The uppermost riser 9, of the folding stairs is provided with two sidebars 15, each ending in a hook 16, these hooks being adapted to hookover the edge of the bunk.

In the folded condition of the stairs the toggles are held adjacent tothe ends of the treads and risers, in the manner shown in Fig. 2, sothat the folded stair may be used as a stool. In raising the uppermostriser, the stairs may be unfolded and on properly engaging the hook 16,with a suitable support, the stairs will be in working condition.

It is of course understood that the legs 18, and the extended togglebars must be of a proper length so that when in use the treads will comein horizontal position.

In Fig. 1, the upper bunk is marked D, and the lower bunk E, the stairsbeing shown in extended position.

The device is simple and inexpensive in construction, and both durableand efficient in operation, and the stairs can be adjusted upon the edgeof a bunk with ease, accuracy and despatch.

'I-Iaving thus described my said invention, what I claim as new anddesire to secure by Letters Patent is:

1. The combination in a folding bunk ing secured to two treads by meansof pins passing through its ears and vthrough the ears of said treads,two pivotally connected stairs, of a stool comprising a top and foursupporting legs, of two downwardly extending apertured ears secured tothe forward corners of said top, two upwardly extending ears secured tothe rear corners of i said top each of-said ears having a, securing(base, of a plurality of treads of a size equal ears at its lowercorners and two outstanding ears at its upper corners, each riserbetoggle bars each having one end pivotally secured to the pinsconnecting said treads to said risers at their-forward'corners, two sidebars each ending in a hook adapted to engage the edge of a bunk securedto the against the outer ends of said treads and risers, as, and in themanner'set forth.

2. The combination wlth a stool COIIIPIlS-r ing a top and foursupporting legs, ofa

plurality of treads and risers said risers being operatively connectedto said treads, a"

set of hook ended bars secured to the uppermost tread, and a pluralityof toggle bars connecting each of said treads and risers whereby all ofsaid'treads, risers, and toggle bars may be compactly folded upon saidstool top, as, and in the manner 'set forth. a r

In testimony whereof I afiiX my signa 'ture, in the presence oftwowitnesses.
